What is the first bird pictured in post #18? We gets lots of those around these parts.
In Europe, they get the name Starling because when in flight, their short wings and short tail make them look something like a 4 pointed star.
In the US, the Starling (also called a Grackle) is a bird with a longer tail and black beak and legs but sports the deep black, iridescent plummage all year long.
But, they are not the same as the Common Blackbird (turdus merula) which has the longer tail, more slender body like the Starling/Grackle but with the orange beak/legs.
Clear as mud, right?
